1. Kabete goat virus was not transmitted from reacting to susceptible
cattle under conditions of close contact.
2. A single doubtful transmission was recorded under conditions of
3. A febrile condition of unknown aetiology transmissible from cattle
to goats was encountered.
4. Urine from reacting animals was non-infective, but faeces in one
out of two cases was infective by drenching.
5. Immunity produced by a single injection of formal-glycerine spleen-vaccine
had completely disappeared after 8 months.
6. Immunity produced by triple vaccination with formal-saline vaccine
had diminished considerably after 8 months.
7. Triple vaccination followed by a single injection of formal-glycerine
spleen vaccine 9 months later produced an immunity which persisted for
at least 20 months.
8. The rapid production of immunity induced by a single injection
of formal-glycerine spleen-vaccine could be used to control the reaction
to K.G.V. An interval of 7 days between vaccine and virus appeared to
be the optimum.
9. Spleen-vaccine prepared from cattle reacting to K.G.V. has an
inferior antigenic potency.
10. The reaction produced by K.G.V. in grade cattle (British breeds
of cattle x Zebu) are severe but usually non-fatal. A durable immunity
follows the reaction.
